IPC: B29C70/84
Filed: 1992-10-16
Abstract: A fast, relatively inexpensive method and simple is disclosed for producing a finished plastic multifocal or progressive lens from a preformed lens which has a predetermined lens correction (i.e., curvature or prescription) at its optical center.  The method comprises providing a mold; providing an optical quality resin composition; providing a preformed plastic lens contacting the preformed lens with the mold such that the surfaces of the preformed lens and the mold form a cavity enclosing the resin composition; and curing the resin composition.  The cavity formed by the preformed lens and the mold is shaped, among other purposes, (1) to correspond to the desired change in curvature, and (2) such that the lens correction at the optical center of the resulting lens is substantially the same (preferably the same) as the predetermined lens correction at the optical center of the preformed lens. The preformed lens may also be cast with a thin nonprescription layer which acts as a carrier for the multifocal or progressive region of the finished lens.  The methods disclosed allow casting of lenses without employing expensive conventional optical gaskets. The methods also allow for simpler relocation of the optical center to the proper position with respect to the multifocal or progressive prescription, preferably without using conventional optical gaskets or optical center movers.

Title: A method for generation of antibodies to cell surface molecules
Inventor: DE BOER MARK
IPC: A61P7/06
Filed: 1993-07-08
Abstract: The present invention relates to a method of generating antibodies directed against cell surface antigens and it uses recom-binant insect cells as immunogens. The insect cells have been transfected with coding regions for a molecule containing a cell sur-face antigen and these antigens are expressed on the surface of the insect cells. Host animals are immunized with these transfect-ed insect cells to generate antibodies directed, against the cell surface antigen. Antibody-producing cells from the host animal are used to generate monoclonal antibody-producing hybridoma cells. Sera and hybridoma supernatants can be tested for the pres-ence of antibodies against the surface antigen, using the transfected cells in a screening assay. Specific antibodies that have been generated by the present method are anti-B7 and anti-CD40 antibodies and they can be used to prevent or treat an antibody-me-diated or immune system disease in a patient. The anti-B7 antibodies can be used to cause T cell, anergy, treat allograft transplant rejection, treat graft versus host disease, and prevent or treat rheumatoid arthritis. An immunosuppressive agent may be co-ad-ministered with the antibody. The anti-CD40 antibodies which bind to the CD40 antigen can be used to prevent the growth or dif-ferentiation of the B cell. Monoclonal antibodies useful in these methods, and epitopes immunoreactive with such monoclonal antibodies are also presented.

Patent CA-2153345-A1 (CA)
Title: Low Polarization Sensitivity Gold Mirrors on Silica
Inventor: FILAS ROBERT WILLIAM
IPC: G02B1/10
Filed: 1995-07-06
Abstract: Gold is useful for infrared polarization-insensitive mirrors on silica. However, gold does not adhere to bare silica. The adherence is enhanced by depositing an optically thin glue layer of Ni-P on a silica surface after sensitization of the surface with SnF2 and activation with PdCl2/HCl. The Ni-P layer is deposited in a thickness sufficient to enhance adherence of gold to the surface of silica but insufficient to act as a barrier to the passage of infrared radiation to or from the gold layer. One measure of the Ni-P thickness is the absorbance of the glue layer of >0.008 at 550 nm (>0.003 at 850 nm) as measured by a spectrophotometer. A 100- 150 nm thick gold layer, deposited by e-beam deposition on this adhesion layer, adheres well enough to pass the commonly used "Scotch tape adhesion test". The ability to make gold adhere to silica with very low optical loss is useful in fabrication of lightwave devices which require the use of reflecting surfaces, such as on optical fibers or waveguides.

Title: Electrical wire fishing tool
Inventor: PUDWELL RONALD P
IPC: H02G1/08
Filed: 1996-01-24
Abstract: It is a tool to help when installing small electrical conductors in conduits. By attaching this tool to the leading end of the conductors or fish tape and filling the outer spring with lubricant, it will realease the lubricant as the tool is pushed. If the tool hits a bend or an obstruction the inner spring is compressed when the plunger is forced along the inside of the outer spring, lubricant is then forced out of the lead end nipple therefore making the bend in the conduit slippery allowing the conductors or fish tape to travel on to the end of the conduit.
